Open Stack

Hi Bart,

Is this script intended to run across multiple clouds to test the basics of
being able to "build a webserver" on any given cloud, aka "AppDev usability
of clouds"?

Hence not being able to use Heat, as Heat doesn't work with AWS, Azure,
GCP, etc.?

Apologies if I've got crossed wires.

I've also love to hear your impression of ask.openstack from an AppDev PoV,
but that for another thread.

Best, Flanders
